On-Line Chart Viewer

The nautical chart is a fundamental tool of marine navigation. It shows water depths, obstructions, aids to navigation, channels, shoreline, and more – hopefully all the information mariners need to navigate safely.

NOAA’s nautical charts are viewable here on-line. Each chart is up-to-date with the most recent Notices to Mariners. Use these on-line charts as a ready reference or planning tool, but you should use one of NOAA’s printed or digital charts on your voyage. Click here to find your closest nautical chart sales agent.
